Abstract. Helix is a high-speed stream cipher with a built-in MAC functionality. On a Pentium II CPU it is about twice as fast as Rijndael or Twofish, and comparable in speed to R...

—In this paper, we present an attack on stream cipher implementations by determining the scan chain structure of the linear feedback shift registers in their implementations. Alt...
SOSEMANUK is a word-oriented stream cipher submitted to the ECRYPT stream cipher project, with a variable-length key between 128 and 256 bits. The algorithm is similar to the strea...
Algebraic attacks on stream ciphers [14] recover the key by solving an overdefined system of multivariate equations. Such attacks can break several interesting cases of LFSR-based ...
